Gigabeat S: Implement MDMA and UDMA disk access for bootloader and main binary. Add a needed SDMA API to check channel errors. Increase audio DMA channels' priority as required. Reads and writes measure faster accross all test_disk tests and especially at 4KB and 1MB.

Gigabeat S: Switch SSI1 and 2 around so that playback can use the shared peripheral DMA with SSI2 which doesn't require use of the peripheral DMA unit-- SSI2 is mapped to the SDMA core address space. Fix some break keywords in get_script_pc(). Use the patched script for mcu_2_app (BSP appears to have neglected to update that). Use _SHP instead of _SP for shared peripheral constants (consistency).

Separate running an SDMA channel from resetting it. It should make usage more flexible since resets are needed only before restarting if aborting transfers (because the script is left awaiting requests, not the next start) which PCM does alot of but other things likely won't.

Gigabeat S: Implement an SDMA API and use it in the PCM driver. Some other miscellaneous adjustments to recording and PCM buffer to accomodate use of physical addresses and cache coherency.
